Why do cows need to chew the cud?

Any cow (or bull, for that matter) that did not chew the cud would lose lots of weight, be less productive of methane gas, and would have a very sore rear end.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
